php - sql1 to get names and sql2 to get Impressions, I need to sort names by Impressions -


hello have project , need me

$sql1 = "select count(*) num table1 column1='1'";      $total_results = mysql_fetch_array(mysql_query($sql1));      $total_results = $total_results[num];      while($row = mysql_fetch_array($sql1))          {  $sql2="select distinct column1 table2 column2='".$row['id']."' , left(date,10) between '".$datefrom."' , '".$dateto."'";  $res=mysql_query($sql2);  }

sql1 names , sql2 impressions, need sort names impressions

name | impressions desc

a | 10

b | 8

c | 7

or

name | impressions asc

c | 7

b | 8

a | 10

thanks attention

i'll add same answer on previous question. can in join instead of separate queries;

select t1.id name, count(distinct t2.column1) impressions table1 t1 left join table2 t2   on t1.id=t2.column2 t1.column1 = 1   , left(date,10) between '2013-01-01' , '2013-12-31' group t1.id order impressions desc

an sqlfiddle test with.
